Uniform Convergence of an Infinite Sequence of Functions
Uniform Convergence
Please see the attached file for the fully formatted problems. Let lambda n be a real decreasing sequence converging to Prove E is compact if and only if = 0. I am assuming compactness here refers to the sequential compactness. This seems to make the most sense. Since this problem is an analysis problem, please be ...continues
Please see the attached file for the fully formatted problems. Consider C[0, 1], the space of real valued continuous functions defined on the unit interval [0, 1]. Let K = C1[0, 1] {f : Z 1 0 f02 1, ||f||1 1} Note that C1[0, 1] C[0, 1], and K C[0, 1]. Show that K is compact in C. I am assuming compactness h ...continues

Real Analysis : Finding a Maximum using Lagrange Multipliers
Please see the attached file for the fully formatted problem. What is the maximum of F = x1 +x2 +x3 +x4 on the intersection of x21 +x22 +x23 + x24 = 1 and x31+ x32+ x33+ x34= 0? As this is an analysis question, please be sure to be rigorous and as detailed as possible.
Poincare's Lemma and its Converse
Please see the attached file for the fully formatted problem. For phi E C2[R3 ! R3], curl grad phi = 0. Prove this. The converse is ”Poincare’s Lemma”: if f E C1[R3 --> R3] and if curl f = 0, then f is a gradient, i.e., f = grad for some 2 C2. Try it this way: if f = grad phi, then phi (x1, x2, x3) = phi(0)+ .... ...continues
Laplacian : Grad and Curl Proof
Please see the attached file for the fully formatted problems. Show that for f E C2(R3 --> R3), grad x curl =grad(div f) - DELTA f
Critical Point : Non-Degenerate
Please see the attached file for full problem description. Show that f(x) = x1x2 + x2x3 + x3x1 has a non - degenerate critical point at x = 0 and describe the shape of f as concretely as possible.
